The contrail from a SpaceX Falcon 9 rocket is seen from Pasadena, Calif., about 150 miles east from its launch site in Vandenberg Air Force Base, Calif., on Friday, Dec. 22, 2017. A reused SpaceX rocket has carried 10 satellites into space from California, leaving behind it a trail of mystery and wonder. The Falcon 9 booster lifted off from coastal Vandenberg Air Force Base shortly before 5:30 p.m. Friday. It carried the latest batch of satellites for Iridium Communications.
